This paper deals with certain technical, operational, and economic considerations and features relating to interactive bidirectional CATV systems developed and installed by TOCOM, Inc. at several locations. Extensive operational field experience has provided TOCOM with a fully-operational two-way system design and production home terminal units that are generating additional, paid services in these systems. Inherent features of the TOCOM system provide faster. more accurate system maintenance techniques and an array of interactive functions, including effective "per-program" pay-TV mechanisms. The services described represent a new market for CATV systems with the TOCOM capability.
